HEATER.

SPECIFICATION forming part of Letters Patent No. 302,305 dated July 22,1884.

' Application filed November 27, 1883. (No model.)

To aZZ whom, it may concern Be it known that I, GEORGE WrrrBoLD, acitizen of the United States of America, re-

siding at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Heaters,of which thefollowing is a specification, reference be ing had therein to theaccompanying drawings.

My invention relates to heating apparatus, and is more especiallyadapted to use in the construction of buildings, &c., where theradiation of heat is desired for the purpose of dry ing the plaster, &c.

The invention consists of the novel devices and combination of devices,as will be described and claimed.

Reference will be made to the accompanying drawings, in which Figure 1is a vertical section of the heater; Fig. 2, afront elevation of thesame, and Fig. 3 a section in line 00 x of Fig. 1.

Like letters refer to like parts in each view.

A represents the shell or casing of the heater, provided with suitablefeet or supports,and having an opening in its top closed by a hingedcover, B. The interior of the heateris divided into compartments by apartition, a,which extends from the front to a point near the rear ofcasing A, is then bent at right angle, and extends a short distancedown, when it is again bent at right angle, and eXtends'to rear of theheater. The space above partition or forms a water-tank, while the spacebelow said partition is divided into a fire-box and ash-pit by afire-grate, G. Grate G is formed of a coil of pipes, which open at oneend through the vertical wall of partition (1 into the water space ortank, while at its opposite end it protrudes through the wall of theheater, and, by suitable couplings, is connected with a short verticalpipe, I), coupled at its upper end to a pipe, 0, inserted through theheater, and opening into the interior thereof a at a point abovepartition 0:. The heater is provided with fire and ash pit doors D D,

suitably located. A smoke-stack, E, rests upon the lower horizontalextension of partition a, and opens through said partition into theash-pit. Smoke-stack E passes up through the water-space, and issuitably connected for the discharge of smoke, and is surrounded bywater when the tank is filled.

The operation will be readily understood. The water-space is filled orpartially filled,and the water passing therefrom fills the coil whichforms the grate. A fire being then kindled on said grate, the watertherein contained is heated, and a circulation is obtained, the heatedwater entering the lower end of the coiLand being discharged, afterpassing therethrough, out of the upper end into the tank again. Thesmoke is.carried through stack E, and said stack is graduallyheatedthereby, and by being surrounded by the water heated by passing throughthe gratecoil. A cock, F, may be tapped into the water-tank forwithdrawing said water.

The course of the draft is indicated by arrows, and is as follows: Afterpassing down through the grate, it then passes up through thesmoke-stack.

What I claim is-,

1.. In a heater, the combination, with the shell A and smoke-stack E, ofthe partition a, bent twice at a right angle to form the water-chamber,fire-box, and ash-pit, and supporting one end of the grate O,substantially as described and shown.

2. In a heater, the combination, with the water-chamber and ash-pitformed by the partition a, bent twice at a right angle, of thesmokestack E, passing through the deepest part of said chamber, andcommunicating with the ash-pit, and the grate O, composed of a coiledpipe communicating with the deepest part of the water-chamber, and againwith the same above the fire-box, substantially as described and shown.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE VVITTBOLD.
